Can you explain better? I am really interested to learn how these things work in other countries!
When back to office, do you have to compile a "reimbursement list", attaching the receipts?
Or you get simply an additional daily wage when working away?
In the latter case, this additional wage is being taxed, or is still treated as tax-exempt reimbursement?
For your info: here in Italy wine or beer (or coke, or coffee, or other drinks) are reimbursed, if included in the same bill as the meal. They are not included if consumed away from meals.
You can be reimbursed in two ways: with the reimbursement list, providing proof-of-purchase with fiscal bills, and with a max cost for each of the two allowed meals per day, or with a "diaria", an additional fixed additional wage, which is fixed but country-dependent. In the latter case, this additional wage is subject to marginal tax (which can be well in excess than 50%).
